The Fujisan lava dome is the youngest eruption product of Takaharayama volcano. This small stratovolcano with associated lava domes is located SW of Nasudake volcano. The latest dated eruption took place about 6,500 years ago. Phreatic explosions along a NW-SE-trending trend were followed by emplacement of the Fujisan lava dome and a cryptodome (an area of lava intrusion where lava did not reach the surface) on the NW side of the dome.
